#28 Errors result in exit 0 on OpenSolaris

[Dave Abrahams]

I'm trying to set up VBoxTool to run on OpenSolaris (happy to push it upstream when it works). The fact that vboxtool fails without a non-zero exit code makes it hard to integrate it cleanly with the SMF (how OpenSolaris runs services). I would like to see the script updated with "set -e" near the top and then, of course, all the changes needed to make it work even if errors occur.

Thanks!
